Abstract

본 발명은 전기보온압력밥솥에 적용되어 뚜껑의 락커와 밥솥본체의 걸림부에 의한 결합상태를 감지하는 뚜껑 열림감지장치에 관한 것으로, 특히, 뚜껑이 완벽하게 걸리지 않은 상황에서는 뚜껑이 결합되지 않았음을 표시하여 뚜껑의 상태를 확인할 수 있도록 하며, 또 취사개시 및 취사도중 등 수시로 뚜껑열림을 감지하여 그에따른 각 주변의 장치들을 적절히 제어함으로써, 안전취사도 가능한 전기보온압력밥솥의 뚜껑열림감지장치에 관한 것으로서, 뚜껑의 일측에 설치된 락커와 밥솥본체의 걸림부 및 버튼에 의해 뚜껑이 결합 또는 결합해제되는 전기보온압력밥솥에 있어서, 상기 버튼(40)에 자석부재(41)를 락커(50)에는 리드스위치(51)를 부설시켜 리드스위치(51)의 단속여부에 따라 뚜껑(30)의 개폐를 마이컴의 입력단(P2)으로 입력하여 주는 뚜껑열림감지부(120)와, 상기 뚜껑열림감지부(120)의 뚜껑열림 감지신호를 입력받아 주변의 출력단을 제어하는 마이컴(130)과; 상기 마이컴(130) 출력단(P4)의 제어출력에 의해 뚜껑결합이 해제된 것을 외부로 표시하여 주는 디스플레이부(150)와; 상기 마이컴(130) 출력단(Pl)의 제어출력에 의해 정전압회로부(100)에서 히터등으로 AC 전원을 공급하는 것을 차단하여 주는 안전장치구동부(110)로 구성된 특징이 있다.The present invention relates to a lid open detecting device applied to the electric heat pressure cooker to detect the coupling state of the lid by the locking portion of the locker and the cooker body, in particular, the lid is not coupled in a situation where the lid is not completely caught. In order to check the condition of the lid, and to detect the lid opening from time to time during cooking and cooking, and to properly control the peripheral devices accordingly, the lid opening detection device of the electric thermal pressure cooker that can be cooked safely Regarding, in an electric thermal pressure cooker in which the lid is coupled or released by the locking portion and the button of the locker and the rice cooker main body installed on one side of the lid, the button 40, the magnet member 41 to the locker 50 The lid is opened by placing the reed switch 51 to input the opening and closing of the lid 30 to the input terminal P2 of the microcomputer according to whether the reed switch 51 is intercepted. A sensing unit 120 and a microcomputer 130 that receives a lid opening detection signal of the lid opening detecting unit 120 and controls an output terminal around the lid opening detecting unit 120; A display unit 150 for displaying to the outside that the cap coupling is released by the control output of the microcomputer 130 and the output terminal P4; The control device 110 of the microcomputer 130, the output terminal (Pl) is characterized in that the safety device driver 110 to block the supply of AC power from the constant voltage circuit unit 100 to the heater.
